The plate cylinder 7 and damping-apparatus 10 also are provided with suitable tripping-mechanisms. The cylinders 7 and 2 are preferably arranged beneath the delivery board 18 so that the printed sheets and various parts of the press can be inspected by an attendant from the delivery end of the machine. For two-colour work, a second offset cylinder with its plate cylinder may be combined with the impression cylinder 11.

Title: Improvements in liquid storing and liquid flow distributing and modulating device
Inventor: KULJIAN HARRY ASDOUR
IPC: F28F25/04
Filed: 1959-06-01
Abstract: 878,782. Emptying tanks. KULJIAN CORPORATION. June 1, 1959, No. 18643/59. Class 21. [Also in Group XIII] A tank 10 has a plurality of upstanding outflow pipes 14, 16, 18, 20 terminating at various levels therein above its base. For a small rate of liquid input to the tank only the lowermost pipes 20 will act as liquid outlets, but as the liquid inflow increases any resulting rise in the liquid to a level above the other pipes causes such pipes to act also as liquid outlets and so increase the rate of discharge. The tank may be used to collect condensate from turbines, whereby any sudden large increments of condensate can be temporarily accommodated whilst discharging through the pipes to heat exchange means before being pumped back into a boiler.

Inventor: BAILEY WILLIAM
IPC: B23B5/00
Filed: 1917-12-15
Abstract: 119,952. Bailey, W. Dec. 15, 1917. Caps and like cupped articles.-Relates to an attachment to a drilling-machine to enable stamped metal caps &c. to be turned, and comprises a tool turret which also serves to carry the work to the rotating spindle which carries an automatically operated chuck and moves axially to take it up and then to present it to the tools. The cap is placed on a spring plunger 18, Fig. 1, mounted on the table 17 which is rotated by the handle 22 to bring the cap below a chuck 2, Fig. 2, of the type described in Specification 118,542, [Class 83 (iii), Metals, Cutting], carried by the rotating spindle 1. The spindle and chuck are moved down to engage the cap 21, the ring 9 striking the fixed plate 11 and thus causing the levers 5 to turn and close the chuck. The spindle together with the ring 9 and the cap 21 then rise, and the table 17 is rotated to bring the tool 23 below the spindle which is again brought down. To ensure that thecentre of the bottom of the cup is surfaced, the tool 23 is moved transversely by a lever 27, link 26, and slide 24, the movement being controlled by a spring 28 and stops 29, 31. The table 17 &c. are again moved and the cap shouldered internally and externally by cutters 33, 35. The spindle 1 is then raised until the ring 9 strikes the plate 10 and the chuck 2 opens to release the finished cap. The table 17 is looked by a spring pin 41 which can be raised by a lever 43.

Title: Improvements in or relating to screw-threaded metal parts
IPC: F16B31/06
Filed: 1934-06-25
Abstract: 425,439. Making screw-threaded parts. GLATTE, E., 14, Kaiser Friedrichstrasse, Charlottenburg, Berlin. June 25, 1934, No. 18770. Convention date, April 25. [Class 83 (iv)] [See also Group XXV] A screw-threaded metal part such as a bolt has a reduced shank portion which tends to increase the fatigue strength of the bolt and during the shaping or by subsequent treatment different tensile strengths are imparted to the different sections of the bolt in correspondence with their sectional dimensions whereby, for instance, the root of the thread, the unreduced shank portion and the reduced shank portion are all adapted to carry substantially the same static load. The reduced shank portion may be formed by cold working to increase the tenacity, or the shank may be turned and subsequently heat treated by high temperature case hardening, or by the nitrogen process, or the shank may be turned oversize and then brought to its correct section by cold rolling or drawing. The thread may be wholly or partly cold rolled and the reduced shank portion also produced wholly or partly by cold working. After shaping is completed the bolt may be heat treated at a temperature between 400 and 500‹ C.

Abstract: 1300301 Read only memory GENERAL INSTRUMENT MICROELECTRONICS Ltd 20 July 1971 [20 April 1970] 18847/70 Heading G4A A read only memory has a semi-conductor substrate of N-type material having diffused regions forming strips of P-type conductivity. The strips are arranged in groups 1, 2, each of which has two sensing or read-out strips 3, 4 a read strip 5 and an output strip 7, strips 5 of a set of groups being coupled by a diffused strip 7 and strips 6 by a diffused strip 8. The strips and substrate are covered by an insulating material on which electrodes 11, 12 are deposited to overlie the substrate between strips 3 or 4 and 5 or 3 or 4 and 6. Electrodes 13, 14 are also deposited to overlie strips 7, 9, and strips 8, 10, The electrodes form insulated field effect devices with their strips and regions. A further insulating material is applied and conductors X, Y, # 1 , # 2  are deposited.  In operation if a bit location associated with an X conductor is to be read a negative going pulse is applied from circuit 19 in phase # 1  time to the appropriate conductor. At each electrode 11 connected to the conductor the voltage on read strip 5 from transistor 7, 9, 13 negatively charges the associated sensing strip 3 or 4. An appropriate Y strip is fed with a negative pulse to transfer any charge from strip 3 or 4 to strip 6 to be read at output 17. A # 2  pulse connects strips 6 to earth to discharge any potential existing.

Title: Improvements in or relating to Vending Machines
IPC: G07F5/22
Filed: 1968-04-22
Abstract: 1,167,682. Vending machine; counting apparatus. VENDO CO. 22 April, 1968 [24 Jan., 1968], No. 18870/68. Headings G4D and G4V. A solid state totalizer for use with a vending machine comprises a first register responsive to coins to accumulate credit therein until the maximum capacity is reached, whereupon a transfer signal is applied to a second register and the first register reset to zero. As described a vending machine includes a fifty-cent totalizer, the first register being responsive to five and ten-cent pieces and the second register twenty-five-cent pieces. On insertion of a five-cent piece, switch 74 opens momentarily charging and discharging a condenser 7 through a zero biased diode gate 88 causing S.C.R. 32 to conduct and indicate a five-cent credit. This zero biases gate 90 and causes S.C.R. 62 to conduct and back bias gate 88. If a ten-cent piece is now inserted, switch 84 closes on its lower contact, discharging condenser 80 through zero biased gate 90 and activating S.C.R. 32. This zero biases gate 92 and turns off S.C.R. 32 through condenser 42, thereby back biasing gate 90. Switch 84 then closes on its upper contact discharging condenser 70 through zero-biased gate 92 to repeat the procedure. When S.C.R. 40 is activated indicating a total credit of twenty-five cents, S.C.R. 62 is turned off, a transfer signal is generated on line 18 causing S.C.R. 124 to conduct and S.C.R.'s 40 and 62 to turn off to clear the first register. The second register operates in a similar manner inputs being from the first register, or, if a 25-cent coin is introduced, condenser 80 discharging along line 148 when switch 86 is closed. When S.C.R. 126 has been activated indicating a credit of fifty cents, relay 172 is operated to close a switch 174, activating dispensing means 178 and a switch 176 which activates an R.C. timer controlling a neon lamp which turns on S.C.R. 164 to reset the second register.
